We Are Rare And Precious Because We Are Alive, Because We Can Think As Well As We Can. We Are Privileged To Influence And Perhaps Control Our Future. I Believe We Have An Obligation To Fight For Life On Earth - Not Just For Ourselves, But For All Those, Humans And Others, Who Came Before Us, And To Whom We Are Beholden, And For All Those Who, If We Are Wise Enough, Will Come After.

We Are, In A Way, Temporary Ambulatory Repositories For Our Nucleic Acids. This Does Not Deny Our Humanity; It Does Not Prevent Us From Pursuing The Good, The True And The Beautiful. But It Would Be A Great Mistake To Ignore Where We Have Come From In Our Attempt To Determine Where We Are Going.

For A Long Time The Human Instinct To Understand Was Thwarted By Facile Religious Explanations.

A Celibate Clergy Is An Especially Good Idea, Because It Tends To Suppress Any Hereditary Propensity Toward Fanaticism.

An Extraterrestrial Being, Newly Arrived On Earth - Scrutinizing What We Mainly Present To Our Children In Television, Radio, Movies, Newspapers, Magazines, The Comics, And Many Books - Might Easily Conclude That We Are Intent On Teaching Them Murder, Rape, Cruelty, Superstition, Credulity, And Consumerism. We Keep At It, And Through Constant Repetition Many Of Them Finally Get It.

A Central Lesson Of Science Is That To Understand Complex Issues (or Even Simple Ones), We Must Try To Free Our Minds Of Dogma And To Guarantee The Freedom To Publish, To Contradict, And To Experiment. Arguments From Authority Are Unacceptable.

For All Its Material Advantages, The Sedentary Life Has Left Us Edgy, Unfulfilled, Even After 400 Generations In Villages And Cities, We Haven't Forgotten: The Open Road Still Softly Calls Like A Nearly Forgotten Song Of Childhood.

In Mozambique, The Story Goes, Monkeys Do Not Talk, Because They Know If They Utter Even A Single Word Some Man Will Come And Put Them To Work.

Our Ancestors Lived Out Of Doors. They Were As Familiar With The Night Sky As Most Of Us Are With Our Favorite Television Programs.

After The Earth Dies, Some 5 Billion Years From Now, After It's Burned To A Crisp, Or Even Swallowed By The Sun, There Will Be Other Worlds And Stars And Galaxies Coming Into Being - And They Will Know Nothing Of A Place Once Called Earth.

The Sky Calls To Us. If We Do Not Destroy Ourselves, We Will One Day Venture To The Stars.

Some Racists Still Reject The Plain Testimony Written In The Dna That All The Races Are Not Only Human But Nearly Indistinguishable. . . .

There Are Many Hypotheses In Physics Of Almost Comparable Brillance And Elegance That Have Been Rejected Because They Did Not Survive Such A Confrontation With Experiment. In My View, The Human Condition Would Be Greatly Improved If Such Confrontations And Willingness To Reject Hypotheses Were A Regular Part Of Our Social, Political, Economic, Religious And Cultural Lives.

If I Finish A Book A Week, I Will Read Only A Few Thousand Books In My Lifetime, About A Tenth Of A Percent Of The Contents Of The Greatest Libraries Of Our Time. The Trick Is To Know Which Books To Read.

Whatever The Reason You're On Mars, I'm Glad You're There, And I Wish I Was With You.

The Candle Flame Gutters. Its Little Pool Of Light Trembles. Darkness Gathers. The Demons Begin To Stir.

We Are...capable Of Using Our Compassion And Our Intelligence, Our Technology And Our Wealth, To Make An Abundant And Meaningful Life For Every Inhabitant Of This Planet. To Enhance Enormously Our Understanding Of The Universe, And To Carry Us To The Stars.

The Surface Of The Earth Is The Shore Of The Cosmic Ocean. On This Shore, We've Learned Most Of What We Know. Recently, We've Waded A Little Way Out, Maybe Ankle-deep, And The Water Seems Inviting. Some Part Of Our Being Knows This Is Where We Came From. We Long To Return, And We Can, Because The Cosmos Is Also Within Us. We're Made Of Star Stuff. We Are A Way For The Cosmos To Know Itself.

The Hole In The Ozone Layer Is A Kind Of Skywriting. At First It Seemed To Spell Out Our Continuing Complacency Before A Witch's Brew Of Deadly Perils. But Perhaps It Really Tells Of A Newfound Talent To Work Together To Protect The Global Environment.

The Method Of Science, As Stodgy And Grumpy As It May Seem, Is Far More Important Than The Findings Of Science.

Stars Are Phoenixes, Rising From Their Own Ashes.

The Values Of Science And The Values Of Democracy Are Concordant, In Many Cases Indistinguishable. Science And Democracy Began - In Their Civilized Incarnations - In The Same Time And Place, Greece In The Seventh And Sixth Centuries B.c. . . . Science Thrives On, Indeed Requires, The Free Exchange Of Ideas; Its Values Are Antithetical To Secrecy. Science Holds To No Special Vantage Points Or Privileged Positions. Both Science And Democracy Encourage Unconventional Opinions And Vigorous Debate. Both Demand Adequate Reason, Coherent Argument, Rigorous Standards Of Evidence And Honesty.

I Don?t Feel Rejected By The Sky. I?m A Part Of It- Tiny, To Be Sure, But Everything Is Tiny Compared To That Overwhelming Immensity.

The Price We Pay For Anticipation Of The Future Is Anxiety About It

Our Intelligence Is Imperfect, Surely, And Newly Arisen; The Ease With Which It Can Be Sweet-talked, Overwhelmed, Or Subverted By Other Hardwired Propensities - Sometimes Themselves Disguised As The Cool Light Of Reason - Is Worrisome.

The Fact That Someone Says Something Doesn't Mean It's True. Doesn't Mean They're Lying, But It Doesn't Mean It's True.

I’m Struck Again By The Irony That Spaceflight-conceived In The Cauldron Of Nationalist Rivalries And Hatreds-brings With It A Stunning Transnational Vision. You Spend Even A Little Time Contemplating The Earth From Orbit And The Most Deeply Engrained Nationalisms Begin To Erode. They Seem The Squabbles Of Mites On A Plum.

Those With The Courage To Explore The Weave And Structure Of The Cosmos, Even Where It Differs Profoundly From Their Wishes And Prejudices, Will Penetrate Its Deepest Mysteries.

The Words "question" And "quest" Are Cognates. Only Through Inquiry Can We Discover Truth.

There Are Naive Questions, Tedious Questions, Ill-phrased Questions, Questions Put After Inadequate Self-criticism. But Every Question Is A Cry To Understand The World. There Is No Such Thing As A Dumb Question.

The Universe Forces Those Who Live In It To Understand It. Those Creatures Who Find Everyday Experience A Muddled Jumble Of Events With No Predictability, No Regularity, Are In Grave Peril. The Universe Belongs To Those Who, At Least To Some Degree, Have Figured It Out.

This Oak Tree And Me, We're Made Of The Same Stuff.

Since, In The Long Run, Every Planetary Society Will Be Endangered By Impacts From Space, Every Surviving Civilization Is Obliged To Become Spacefaring — Not Because Of Exploratory Or Romantic Zeal, But For The Most Practical Reason Imaginable: Staying Alive.

In The Way That Scepticism Is Sometimes Applied To Issues Of Public Concern, There Is A Tendency To Belittle, To Condescend, To Ignore The Fact That, Deluded Or Not, Supporters Of Superstition And Pseudoscience Are Human Beings With Real Feelings, Who, Like The Sceptics, Are Trying To Figure Out How The World Works And What Our Role In It Might Be. Their Motives Are In Many Cases Consonant With Science. If Their Culture Has Not Given Them All The Tools They Need To Pursue This Great Quest, Let Us Temper Our Criticism With Kindness. None Of Us Comes Fully Equipped.

Many Religions Have Attempted To Make Statues Of Their Gods Very Large, And The Idea, I Suppose, Is To Make Us Feel Small. But If That's Their Purpose, They Can Keep Their Paltry Icons. We Need Only Look Up If We Wish To Feel Small.

The Immense Distances To The Stars And The Galaxies Mean That We See Everything Ins Pace Int He Past, Some As They Were Before The Earth Came To Be. Telescopes Are Time Machines.

If We Are To Survive, Our Loyalties Must Be Broadened Further, To Include The Whole Human Community, The Entire Planet Earth.

Nature Does Not Always Conform To Our Predispositions And Preferences, To What We Deem Comfortable And Easy To Understand.

It Will Not Be We Who Reach Alpha Centauri, And The Other Nearby Stars. It Will Be A Species Very Like Us - But With More Of Our Strengths And Fewer Of Our Weaknesses.

Science Arouses A Soaring Sense Of Wonder. But So Does Pseudoscience. Sparse And Poor Popularizations Of Science Abandon Ecological Niches That Pseudoscience Promptly Fills. If It Were Widely Understood That Claims To Knowledge Require Adequate Evidence Before They Can Be Accepted, There Would Be No Room For Pseudoscience.

Our Concern For The Future Can Be Tested By How Well We Support Our Libraries.

We Are An Intelligent Species And The Use Of Our Intelligence Quite Properly Gives Us Pleasure. In This Respect The Brain Is Like A Muscle. When We Think Well, We Feel Good. Understanding Is A Kind Of Ecstasy.

If There Is Life, Then I Believe We Should Do Nothing To Disturb That Life. Mars Then, Belongs To The Martians, Even If They Are Microbes.

Except In Pure Mathematics, Nothing Is Known For Certain (although Much Is Certainly False).

The Claim Is Also Sometimes Made That Science Is As Arbitrary Or Irrational As All Other Claims To Knowledge, Or That Reason Itself Is An Illusion. As Ethan Allen Said Those Who Invalidate Reason Ought Seriously To Consider Whether They Argue Against Reason With Or Without Reason; If With Reason, Then They Establish The Principle That They Are Labouring To Dethrone. If They Argue Without Reason, Which They Must Do, In Order To Be Consistent With Themselves, They Are Out Of Reach Of Rational Conviction, Nor Do They Deserve A Rational Argument.

I Set Before You Two Ways: You Can Use Your Technology To Destroy Yourselves Or To Carry You To The Planets And The Stars. It's Up To You.

I Believe Our Future Depends Powerfully On How Well We Understand This Cosmos In Which We Float, Like A Mote Of Dust In The Morning Sky.

One Of The Greatest Gifts Adults Can Give - To Their Offspring And To Their Society - Is To Read To Children.

How Is It That Hardly Any Major Religion Has Looked At Science And Concluded, “this Is Better Than We Thought! The Universe Is Much Bigger Than Our Prophets Said, Grander, More Subtle, More Elegant?

Cosmos Is A Greek Word For The Order Of The Universe. It Is, In A Way, The Opposite Of Chaos. It Implies The Deep Interconnectedness Of All Things. It Conveys Awe For The Intricate And Subtle Way In Which The Universe Is Put Together.

The Idea That God Is An Oversized White Male With A Flowing Beard, Who Sits In The Sky And Tallies The Fall Of Every Sparrow Is Ludicrous. But If By 'god,' One Means The Set Of Physical Laws That Govern The Universe, Then Clearly There Is Such A God. This God Is Emotionally Unsatisfying... It Does Not Make Much Sense To Pray To The Law Of Gravity.

The Suppression Of Uncomfortable Ideas May Be Common In Religion Or In Politics, But It Is Not The Path To Knowledge; It Has No In The Endeavor Of Science. We Do Not Know In Advance Who Will Discover Fundamental Insights.

Our Planet Is A Lonely Speck In The Great Enveloping Cosmic Dark. In Our Obscurity, In All This Vastness, There Is No Hint That Help Will Come From Elsewhere To Save Us From Ourselves.

The Open Road Still Softly Calls.

You Could Just As Well Say That An Agnostic Is A Deeply Religious Person With At Least A Rudimentary Knowledge Of Human Fallibility.

The Earth Is The Only World Known So Far To Harbor Life. There Is Nowhere Else, At Least In The Near Future, To Which Our Species Could Migrate. Visit, Yes. Settle, Not Yet. Like It Or Not, For The Moment The Earth Is Where We Make Our Stand. It Has Been Said That Astronomy Is A Humbling And Character-building Experience..... To Me, It Underscores Our Responsibility To Deal More Kindly With One Another, And To Preserve And Cherish The Pale Blue Dot, The Only Home We've Ever Known.

Somewhere, Something Incredible Is Waiting To Be Known.

The Nuclear Arms Race Is Like Two Sworn Enemies Standing Waist Deep In Gasoline, One With Three Matches, The Other With Five.

Scientists Constantly Get Clobbered With The Idea That We Spent 27 Billion Dollars On The Apollo Programs, And Are Asked "what More Do You Want?" We Didn't Spend It; It Was Done For Political Reasons. ... Apollo Was A Response To The Bay Of Pigs Fiasco And To The Successful Orbital Flight Of Yuri Gagarin. President Kennedy's Objective Was Not To Find Out The Origin Of The Moon By The End Of The Decade; Rather It Was To Put A Man On The Moon And Bring Him Back, And We Did That.

We Wish To Find The Truth, No Matter Where It Lies. But To Find The Truth We Need Imagination And Skepticism Both. We Will Not Be Afraid To Speculate, But We Will Be Careful To Distinguish Speculation From Fact.

Where We Have Strong Emotions, We're Liable To Fool Ourselves.

We All Have A Thirst For Wonder. It's A Deeply Human Quality. Science And Religion Are Both Bound Up With It. What I'm Saying Is, You Don't Have To Make Stories Up, You Don't Have To Exaggerate. There's Wonder And Awe Enough In The Real World. Nature's A Lot Better At Inventing Wonders Than We Are.

Who Will Speak For Planet Earth?

There Are Lots Of Ways To Communicate What We Know, But Few Ways To Communicate What We Feel. Music Is One Way To Communicate Emotions.

The Bill Of Rights Decoupled Religion From The State, In Part Because So Many Religions Were Steeped In An Absolutist Frame Of Mind - Each Convinced That It Alone Had A Monopoly On The Truth And Therefore Eager For The State To Impose This Truth On Others.

The Lifetime Of A Human Being Is Measured By Decades, The Lifetime Of The Sun Is A Hundred Million Times Longer. Compared To A Star, We Are Like Mayflies, Fleeting Ephemeral Creatures Who Live Out Their Lives In The Course Of A Single Day.

The Cosmos Is Full Beyond Measure Of Elegant Truths; Of Exquisite Interrelationships; Of The Awesome Machinery Of Nature.

I Don't Want To Believe. I Want To Know.

We Have Also Arranged Things So That Almost No One Understands Science And Technology. This Is A Prescription For Disaster. We Might Get Away With It For A While, But Sooner Or Later This Combustible Mixture Of Ignorance And Power Is Going To Blow Up In Our Faces.

Clutching Our Crystals And Religiously Consulting Our Horoscopes, Our Critical Faculties In Steep Decline, Unable To Distinguish Between What's True And What Feels Good, We Slide, Almost Without Noticing, Into Superstition And Darkness.

But The Fact That Some Geniuses Were Laughed At Does Not Imply That All Who Are Laughed At Are Geniuses. They Laughed At Columbus, They Laughed At Fulton, They Laughed At The Wright Brothers. But They Also Laughed At Bozo The Clown.

You Mean Am I For It Or Against It? You Think This Is A Key Question I'm Going To Be Asked On Vega, And You Want To Make Sure I Give The Right Answer? Okay. Overpopulation Is Why I'm In Favor Of Homosexuality And A Celibate Clergy. A Celibate Clergy Is An Especially Good Idea, Because It Tends To Suppress Any Hereditary Propensity Toward Fanaticism.

Science Is Based On Experiment, On A Willingness To Challenge Old Dogma, On An Openness To See The Universe As It Really Is. Accordingly, Science Sometimes Requires Courage - At The Very Least The Courage To Question The Conventional Wisdom.

We Are At A Crossroads In Human History. Never Before Has There Been A Moment So Simultaneously Perilous And Promising. We Are The First Species To Have Taken Evolution Into Our Own Hands.

There Is Today-in A Time When Old Beliefs Are Withering-a Kind Of Philosophical Hunger, A Need To Know Who We Are And How We Got Here. It Is An On-going Search, Often Unconscious, For A Cosmic Perspective For Humanity

For Small Creatures Such As We The Vastness Is Bearable Only Through Love.

One Trend That Bothers Me Is The Glorification Of Stupidity, That The Media Is Reassuring People It's Alright Not To Know Anything. That To Me Is Far More Dangerous Than A Little Pornography On The Internet.

The Nitrogen In Our Dna, The Calcium In Our Teeth, The Iron In Our Blood, The Carbon In Our Apple Pies Were Made In The Interiors Of Collapsing Stars. We Are Made Of Starstuff.

I Think The Discomfort That Some People Feel In Going To The Monkey Cages At The Zoo Is A Warning Sign.

There Are As Many Atoms In One Molecule Of Dna As There Are Stars In A Typical Galaxy.

Science Is Only A Latin Word For Knowledge

The Cosmos Is All That Is Or Was Or Ever Will Be. Our Feeblest Contemplations Of The Cosmos Stir Us -- There Is A Tingling In The Spine, A Catch In The Voice, A Faint Sensation, As If A Distant Memory, Of Falling From A Height. We Know We Are Approaching The Greatest Of Mysteries.

As The Ancient Myth Makers Knew, We Are Children Equally Of The Earth And The Sky.

Our Children Long For Realistic Maps Of The Future That They Can Be Proud Of. Where Are The Cartographers Of Human Purpose?

The Prediction I Can Make With The Highest Confidence Is That The Most Amazing Discoveries Will Be The Ones We Are Not Today Wise Enough To Foresee.

Because Men, Compared To Male Chimps, Have Such Relatively Small Testicles (large Testicles Indicate A Species Where Many Males Mate, One After The Other, With The Same Female), We Might Guess That Promiscuous Societies Were Uncommon In The Immediate Human Past.

Perhaps The Depth Of Love Can Be Calibrated By The Number Of Different Selves That Are Actively Involved In A Given Relationship.

The Wind Whips Through The Canyons Of The American Southwest, And There Is No One To Hear It But Us - A Reminder Of The 40,000 Generations Of Thinking Men And Women Who Preceded Us, About Whom We Know Almost Nothing, Upon Whom Our Civilization Is Based.

If We Say That God Has Always Been, Why Not Save A Step And Conclude That The Universe Has Always Been?

Time Spent With Children Is Time Well Spent. Their Little Minds Are Not Constrained By 'reality' Or Focused Upon Goals. Anything And Everything Is Possible. Imagination Will Often Carry Us To Worlds That Never Were. But Without It We Go Nowhere.

The Visions We Offer Our Children Shape The Future. It _matters_ What Those Visions Are. Often They Become Self-fulfilling Prophecies. Dreams Are Maps.

If We Continue To Accumulate Only Power And Not Wisdom, We Will Surely Destroy Ourselves.

The Cosmos Is Within Us. We Are Made Of Star Stuff

If We Are Merely Matter Intricately Assembled, Is This Really Demeaning? If There's Nothing Here But Atoms, Does That Make Us Less Or Does That Make Matter More?

But, Jefferson Worried That The People - And The Argument Goes Back To Thucydides And Aristotle - Are Easily Misled. He Also Stressed, Passionately And Repeatedly, That It Was Essential For The People To Understand The Risks And Benefits Of Government, To Educate Themselves, And To Involve Themselves In The Political Process. Without That, He Said, The Wolves Will Take Over.

We Are Prodding, Challenging, Seeking Contradictions Or Small, Persistent Residual Errors, Proposing Alternative Explanations, Encouraging Heresy. We Give Our Highest Rewards To Those Who Convincingly Disprove Established Beliefs.

We Are The Only Species On The Planet, So Far As We Know, To Have Invented A Communal Memory Stored Neither In Our Genes Nor In Our Brains. The Warehouse Of This Memory Is Called The Library

Since World War Ii, Japan Has Spawned Enormous Numbers Of New Religions Featuring The Supernatural.... In Thailand, Diseases Are Treated With Pills Manufactured From Pulverized Sacred Scripture. Witches Are Today Being Burned In South Africa.... The Worldwide Tm [transcendental Meditation] Organization Has An Estimated Valuation Of $3 Billion. For A Fee, They Promise To Make You Invisible, To Enable You To Fly.

If We Could Travel Into The Past, It's Mind-boggling What Would Be Possible. For One Thing, History Would Become An Experimental Science, Which It Certainly Isn't Today. The Possible Insights Into Our Own Past And Nature And Origins Would Be Dazzling. For Another, We Would Be Facing The Deep Paradoxes Of Interfering With The Scheme Of Causality That Has Led To Our Own Time And Ourselves. I Have No Idea Whether It's Possible, But It's Certainly Worth Exploring.

Perhaps, In Retrospect, There Would Be Little Motivation Even For Malevolent Extraterrestrials To Attack The Earth; Perhaps, After A Preliminary Survey, They Might Decide It Is More Expedient Just To Be Patient For A Little While And Wait For Us To Self-destruct.

Our Perceptions Are Fallible. We Sometimes See What Isn't There. We Are Prey To Optical Illusions. Occasionally We Hallucinate. We Are Error-prone.

Optical Illusions

Skeptical Scrutiny Is The Means, In Both Science And Religion, By Which Deep Thoughts Can Be Winnowed From Deep Nonsense.

Valid Criticism Does You A Favor.

There Is A Lurking Fear That Some Things Are Not “meant" To Be Known, That Some Inquiries Are Too Dangerous For Human Beings To Make.

The Truth May Be Puzzling. It May Take Some Work To Grapple With. It May Be Counterintuitive. It May Contradict Deeply Held Prejudices. It May Not Be Consonant With What We Desperately Want To Be True. But Our Preferences Do Not Determine What's True.

It Seems Madness To Say, 'we're Worried That They're Going To Become Addicted To Marijuana' -- There's No Evidence Whatever That It's An Addictive Drug, But Even If It Were, These People Are Dying, What Are We Saving Them From?

There Are Many Other (besides Testosterone) Behaviour-eliciting Hormones Fundamental For Humen Well-being, Including Estrogen And Progesterone In Females. The Fact That Complex Behavioural Patterns Can Be Triggered By A Tiny Concentration Of Moleculas Coursing Through The Bloodstream, And That Different Animals Of The Same Species Generate Different Amounts Of These Hormones, Is Something Worth Thinking About When It's Time To Judge Such Matters As Free Will, Individual Responsibility, And Law And Order.

What's The Harm Of A Little Mystification? It Sure Beats Boring Statistical Analyses.

The Vast Distances That Separate The Stars Are Providential. Beings And Worlds Are Quarantined From One Another. The Quarantine Is Lifted Only For Those With Sufficient Self-knowledge And Judgment To Have Safely Traveled From Star To Star.

In All Our Searching, The Only Thing We've Found That Makes The Emptiness Bearable Is Each Other.

All Over The World There Are Enormous Numbers Of Smart, Even Gifted, People Who Harbor A Passion For Science. But That Passion Is Unrequited. Surveys Suggest That Some 95% Of Americans Are "scientifically Illiterate." That's...the Same Fraction...of Slaves Who Were Illiterate Before The Civil War.

Not Explaining Science Seems To Me Perverse. When You're In Love, You Want To Tell The World.

People Are Not Stupid. They Believe Things For Reasons. The Last Way For Skeptics To Get The Attention Of Bright, Curious, Intelligent People Is To Belittle Or Condescend Or To Show Arrogance Toward Their Beliefs.

If We Offer Too Much Silent Assent About Mysticism And Superstition - Even When It Seems To Be Doing A Little Good - We Abet A General Climate In Which Scepticism Is Considered Impolite, Science Tiresome, And Rigorous Thinking Somehow Stuffy And Inappropriate.

In The Vastness Of The Cosmos There Must Be Other Civilizations Far Older And More Advanced Than Ours.

Imagine A Room Awash In Gasoline, And There Are Two Implacable Enemies In That Room. One Of Them Has Nine Thousand Matches. The Other Has Seven Thousand Matches. Each Of Them Is Concerned About Who's Ahead, Who's Stronger. Well That's The Kind Of Situation We Are Actually In. The Amount Of Weapons That Are Available To The United States And The Soviet Union Are So Bloated, So Grossly In Excess Of What's Needed To Dissuade The Other, That If It Weren't So Tragic, It Would Be Laughable. What Is Necessary Is To Reduce The Matches And To Clean Up The Gasoline.

[kepler] Preferred The Hard Truth To His Dearest Illusions, And That Is The Heart Of Science.

Frederick Douglas Taught That Literacy Is The Path From Slavery To Freedom. There Are Many Kinds Of Slavery And Many Kinds Of Freedom, But Reading Is Still The Path.

If You Wish To Make An Apple Pie From Scratch, You Must First Invent The Universe.

There Are Huge Advertising Budgets Only When There's No Difference Between The Products. If The Products Really Were Different, People Would Buy The One That's Better. Advertising Teaches People Not To Trust Their Judgment. Advertising Teaches People To Be Stupid.

The Earth Is A Place. It Is By No Means The Only Place. It Is Not Even A Typical Place.

We Live In A Society Exquisitely Dependent On Science And Technology And Yet Have Cleverly Arranged Things So That Almost No One Understands Science And Technology.

Information Society

The Gears Of Poverty, Ignorance, Hopelessness And Low Self-esteem Interact To Create A Kind Of Perpetual Failure Machine That Grinds Down Dreams From Generation To Generation. We All Bear The Cost Of Keeping It Running. Illiteracy Is Its Linchpin.

I Believe That Part Of What Propels Science Is The Thirst For Wonder. It's A Very Powerful Emotion. All Children Feel It. In A First Grade Classroom Everybody Feels It; In A Twelfth Grade Classroom Almost Nobody Feels It, Or At Least Acknowledges It. Something Happens Between First And Twelfth Grade, And It's Not Just Puberty. Not Only Do The Schools And The Media Not Teach Much Skepticism, There Is Also Little Encouragement Of This Stirring Sense Of Wonder. Science And Pseudoscience Both Arouse That Feeling. Poor Popularizations Of Science Establish An Ecological Niche For Pseudoscience.

I Would Love To Believe That When I Die I Will Live Again, That Some Thinking, Feeling, Remembering Part Of Me Will Continue. But As Much As I Want To Believe That, And Despite The Ancient And Worldwide Cultural Traditions That Assert An Afterlife, I Know Of Nothing To Suggest That It Is More Than Wishful Thinking.

The Size And Age Of The Cosmos Are Beyond Ordinary Human Understanding. Lost Somewhere Between Immensity And Eternity Is Our Tiny Planetary Home.

Your God Is Too Small For My Universe.

What Does It Mean For A Civilisation To Be A Million Years Old? We Have Had Radio Telescopes And Spaceships For A Few Decades; Our Technical Civilisation Is A Few Hundred Years Old ... An Advanced Civilisation Millions Of Years Old Is As Much Beyond Us As We Are Beyond A Bushbaby Or A Macaque

A Single Message From Space Will Show That It Is Possible To Live Through Technological Adolescence. . . . It Is Possible That The Future Of Human Civilization Depends On The Receipt Of Interstellar Messages.

We Are The Children Equally Of The Sky And The Earth.

Chlorine Is A Deadly Poison Gas Employed On European Battlefields In World War I. Sodium Is A Corrosive Metal Which Burns Upon Contact With Water. Together They Make A Placid And Unpoisonous Material, Table Salt. Why Each Of These Substances Has The Properties It Does Is A Subject Called Chemistry.

Philosophers And Scientists Confidently Offer Up Traits Said To Be Uniquely Human, And The Monkeys And Apes Casually Knock Them Down -- Toppling The Pretension That Humans Constitute Some Sort Of Biological Aristocracy Among The Beings On Earth.

We Live In A Vast And Awesome Universe In Which, Daily, Suns Are Made And Worlds Destroyed, Where Humanity Clings To An Obscure Clod Of Rock.

The Uniqueness Of Humans Has Been Claimed On Many Grounds, But Most Often Because Of Our Tool-making, Culture, Language, Reason And Morality. We Have Them, The Other Animals Don't, And -- So The Argument Goes -- That's That.

The Difference Between Physics And Metaphysics Is Not That The Practitioners Of One Are Smarter Than The Practitioners Of The Other. The Difference Is That The Metaphysicist Has No Laboratory.

I Promise To Question Everything My Leaders Tell Me. I Promise To Use My Critical Faculties. I Promise To Develop My Independence Of Thought. I Promise To Educate Myself So I Can Make My Own Judgments.

The Secrets Of Evolution Are Death And Time-the Deaths Of Enormous Numbers Of Lifeforms That Were Imperfectly Adapted To The Environment; And Time For A Long Succession Of Small Mutations.

We Need To Reduce Military Budgets; Raise Living Standards; Engender Respect For Learning; Support Science, Scholarship, Invention, And Industry; Promote Free Inquiry; Reduce Domestic Coercion; Involve The Workers More In Managerial Decisions; And Promote Genuine Respect And Understanding Derived From An Acknowledgement Of Our Common Humanity And Our Common Jeopardy.

Common Humanity

If The Greenhouse Effect Is A Blanket In Which We Wrap Ourselves To Keep Warm, Nuclear Winter Kicks The Blanket Off.

The Hindu Religion Is The Only One Of The World’s Great Faiths Dedicated To The Idea That The Cosmos Itself Undergoes An Immense, Indeed An Infinite, Number Of Deaths And Rebirths. It Is The Only Religion In Which The Time Scales Correspond, No Doubt By Accident, To Those Of Modern Scientific Cosmology. Its Cycles Run From Our Ordinary Day And Night To A Day And Night Of Brahma, 8.64 Billion Years Long, Longer Than The Age Of The Earth Or The Sun And About Half The Time Since The Big Bang.

History Is Full Of People Who Out Of Fear, Or Ignorance, Or Lust For Power Has Destroyed Knowledge Of Immeasurable Value Which Truly Belongs To Us All. We Must Not Let It Happen Again.

An Atheist Has To Know A Lot More Than I Know. An Atheist Is Someone Who Knows There Is No God. By Some Definitions Atheism Is Very Stupid.

There Is No God

There Is Every Reason To Think That In The Coming Years Mars And Its Mysteries Will Become Increasingly Familiar To The Inhabitants Of The Planet Earth.

For All Our Conceits About Being The Center Of The Universe, We Live In A Routine Planet Of A Humdrum Star Stuck Away In An Obscure Corner ... On An Unexceptional Galaxy Which Is One Of About 100 Billion Galaxies. ... That Is The Fundamental Fact Of The Universe We Inhabit, And It Is Very Good For Us To Understand That.

At The Heart Of Science Is An Essential Balance Between Two Seemingly Contradictory Attitudes-an Openness To New Ideas, No Matter How Bizarre Or Counterintuitive They May Be, And The Most Ruthless Skeptical Scrutiny Of All Ideas, Old And New. This Is How Deep Truths Are Winnowed From Deep Nonsense.

Absolute Certainty Will Always Elude Us. We Will Always Be Mired In Error. The Most Each Generation Can Hope For Is To Reduce The Error. . . .

When A Honeybee Dies It Releases A Death Pheromone, A Characteristic Odour That Signals The Survivors To Remove It From The Hive. The Corpse Is Promptly Pushed And Tugged Out Of The Hive. The Death Pheromone Is Oleic Acid. What Happens If A Live Bee Is Dabbed With A Drop Of Oleic Acid? Then No Matter How Strapping And Vigourous It Might Be, It Is Carried Kicking And Screaming Out Of The Hive.

I'm Only A Four-dimensional Creature. Haven't Got A Clue How To Visualise Infinity. Even Einstein Hadn't. I Know Because I Asked Him

There Are Many Hypotheses In Science Which Are Wrong. That’s Perfectly All Right: It’s The Aperture To Finding Out What’s Right. Science Is A Self-correcting Process.

And After We Returned To The Savannahs And Abandoned The Trees, Did We Long For Those Great Graceful Leaps And Ecstatic Moments Of Weightlessness In The Shafts Of Sunlight Of The Forest Roof?

Science Is A Way To Call The Bluff Of Those Who Only Pretend To Knowledge. It Is A Bulwark Against Mysticism, Against Superstition, Against Religion Misapplied To Where It Has No Business Being.

Science Is Far From A Perfect Instrument Of Knowledge. It's Just The Best We Have.

Our Loyalties Are To The Species And The Planet. We Speak For Earth.

If Chimpanzees Have Consciousness, If They Are Capable Of Abstractions, Do They Not Have What Until Now Has Been Described As 'human Rights'? How Smart Does A Chimp Have To Be Before Killing Him Constitutes Murder?

My Deeply Held Belief Is That If A God Of Anything Like The Traditional Sort Exists, Our Curiosity And Intelligence Are Provided By Such A God. We Would Be Unappreciative Of Those Gifts (as Well As Unable To Take Such A Course Of Action) If We Suppressed Our Passion To Explore The Universe And Ourselves. On The Other Hand, If Such A Traditional God Does Not Exist, Our Curiosity And Our Intelligence Are The Essential Tools For Managing Our Survival. In Either Case, The Enterprise Of Knowledge Is Consistent With Both Science And Religion, And Is Essential For The Welfare Of The Human Species.

We Are Made Of Starstuff.

The Surface Of The Earth Is The Shore Of The Cosmic Ocean. From It We Have Learned Most Of What We Know. Recently, We Have Waded A Little Out To Sea, Enough To Dampen Our Toes Or, At Most, Wet Our Ankles. The Water Seems Inviting. The Ocean Calls.

We Began As Wanderers, And We Are Wanderers Still.

The Simplest Thought, Like The Concept Of The Number One, Has An Elaborate Logical Underpinning.

For All Our Failings, Despite Our Limitations And Fallibilities, We Humans Are Capable Of Greatness.

Your Religion Assumes That People Are Children And Need A Boogeyman So They'll Behave. You Want People To Believe In God So They'll Obey The Law. That's The Only Means That Occurs To You: A Strict Secular Police Force, And The Threat Of Punishment By An All-seeing God For Whatever The Police Overlook. You Sell Human Beings Short.

Science Is Merely An Extremely Powerful Method Of Winnowing What's True From What Feels Good.

On The Day That We Do Discover That We Are Not Alone, Our Society May Begin To Evolve And Transform In Some Incredible And Wondrous New Ways.

The Beauty Of A Living Thing Is Not The Atoms That Go Into It, But The Way Those Atoms Are Put Together. Information Distilled Over 4 Billion Years Of Biological Evolution. Incidentally, All The Organisms On The Earth Are Made Essentially Of That Stuff. An Eyedropper Full Of That Liquid Could Be Used To Make A Caterpillar Or A Petunia If Only We Knew How To Put The Components Together.

By Looking Far Out Into Space We Are Also Looking Far Back Into Time, Back Toward The Horizon Of The Universe, Back Toward The Epoch Of The Big Bang.

Across The Sea Of Space, The Stars Are Other Suns.

We On Earth Have Just Awakened To The Great Oceans Of Space And Time From Which We Have Emerged. We Are The Legacy Of 15 Billion Years Of Cosmic Evolution. We Have A Choice: We Can Enhance Life And Come To Know The Universe That Made Us, Or We Can Squander Our 15 Billion-year Heritage In Meaningless Self-destruction. What Happens In The First Second Of The Next Cosmic Year Depends On What We Do, Here And Now, With Our Intelligence And Our Knowledge Of The Cosmos.

Think Of How Many Religions Attempt To Validate Themselves With Prophecy. Think Of How Many People Rely On These Prophecies, However Vague, However Unfulfilled, To Support Or Prop Up Their Beliefs. Yet Has There Ever Been A Religion With The Prophetic Accuracy And Reliability Of Science? ... No Other Human Institution Comes Close.

I Think If We Ever Reach The Point Where We Think We Thoroughly Understand Who We Are And Where We Came From, We Will Have Failed.

Human History Can Be Viewed As A Slowly Dawning Awareness That We Are Members Of A Larger Group Groups Of People From Divergent Ethnic And Cultural Backgrounds Working In Some Sense Together [is] Surely A Humanizing And Character Building Experience. If We Are To Survive, Our Loyalties Must Be Broadened Further, To Include The Whole Human Community, The Entire Planet Earth.

What Is Called For Is An Exquisite Balance Between Two Conflicting Needs: The Most Skeptical Scrutiny Of All Hypotheses That Are Served Up To Us And At The Same Time A Great Openness To New Ideas. If You Are Only Skeptical, Then No New Ideas Make It Through To You. On The Other Hand, If You Are Open To The Point Of Gullibility And Have Not An Ounce Of Skeptical Sense In You, Then You Cannot Distinguish Useful Ideas From The Worthless Ones.

It's Perilous And Foolhardy For The Average Citizen To Remain Ignorant About Global Warming, Say, Or Ozone Depletion, Air Pollution, Toxic And Radioactive Wastes, Acid Rain, Topsoil Erosion, Tropical Deforestation, Exponential Population Growth. Jobs And Wages Depend On Science And Technology.
